Title: Internal combustion engine and cam drive mechanism therefor
Inventor: TSOI-HEI MA THOMAS
IPC: F01L1/352
Filed: 1982-04-08
Abstract: An internal combustion engine has n cylinders, a piston in each cylinder connected to a crankshaft each piston being in phase or out of phase with the others by A° or a multiple thereof (A = 720/n), cams for actuating inlet and exhaust valves to each cylinder and a cam drive mechanism which rotates the cams in phased relationship with the crankshaft to open the valves in sequence for a desired angle of rotation of the crankshaft. The cam drive mechanism includes means for combining the rotational movement of the cams with a phased oscillatory movement of variable amplitude about the axis of rotation at a frequency of f times the crankshaft frequency so that the period over which the valves are opened and/or their timings is variable, f having the following values:-           and f = n/2 when n = 3 or more 
     The selection of the frequency of the oscillations allows all the cams to be mounted on the same camshaft.

Abstract: A connector for a fiber optic cable securely retains the optical fiber without the use of adhesives, and uses a basic assembly step to simultaneously retain the optical fiber. In a first embodiment, the step of crimping a crimping ferrule to retain strength fiber members of the fiber optic cable simultaneously collapses a portion of the connector to securely retain the optical fiber in the connector. In a second embodiment of the invention, the step of inserting an inner member into the connector body causes an end portion to collapse, securely retaining the optical fiber, and may also cause an intermediate portion of the inner member to collapse, securely retaining a buffer or inner jacket layer. Such a fiber optic connector may be made either entirely of metal, or of plastic, without substantial structural modification, as appropriate for use in its intended environment.

Abstract: The blowing, metering and distributing assembly 4 (Figure 2) of a liquid or air flows solids distributor and the extended distribution members are suspended from the chassis 1 by four downwardly converging rigid links 5, each having ball swivel joints 6 at its two ends. Due to the high polar inertia of the suspended assembly, it will not respond to transient yawing, rolling or pitching movements of the chassis but if such movements are sustained, the assembly will re-align to some new rest position. In other embodiments, the number and/or direction of convergence of the suspension links is varied from those shown in Figure 2. The assembly is particularly useful in certain types of agricultural machinery where the operative part of the machine has to be suspended from the body portion of the machine.

Abstract: In a maskless metal cladding process for plating an existing metallurgical pattern (13), a protective layer (16) is utilized to isolate those areas of underlying metallurgy on which additional metal plating is not desired. The layer acts as an isolation barrier to protect the underlying metallurgy from deposition and subsequent diffusion of the heavy metal overlay (17). The composition of the protective layer is selected as one having sufficient mechanical integrity to withstand process handling and support the gold overlay and having the thermal integrity to withstand the high temperatures reached during metal sputtering and diffusion processes. The isolation barrier layer has an organic component as a binder which thermally decomposes, either in a heating step before metal deposition or during the diffusion cycle, leaving no carbonaceous residue but leaving an inert, inorganic standoff to support the metal. After diffusion of the metal, the remaining inorganic standoff layer, overlying metal and any undiffused metal remaining on the non-patterned substrate is easily removed by a standard technique, such as ultrasonics.
